Loud pop followed by smoking mother board.

[Jacob Vile]

Hi, I guess I just suck at building computers because I get a new crippling problem every year.

So after working fine for almost an entire year, my computer decides to shut off mid game. When I tried to turn it back on, nothing happened — no light, no spinning fans, nothing.

So I thought it may be the PSU breaking, and promptly bought another one (although this one had a lower wattage). I replaced my 860w with a 600w psu.

After installing the new PSU, I was greeted with quick poping noises, followed by my motherboard smoking.

It thick smoke came from the stair-looking protrusions shown here:

Understand I am by no means a professional, but the motherboard was working flawlessly before (although I have replaced it in the past).

Are my other parts ok? Do I have to buy a new mobo/psu?

Specs:

• Corsair 860w modular PSU (which I replaced with a Corsair 600w non-modular PSU).

• Gtx 970 GPU

• AMD fx8350 CPU

• MSI 970A-G46 mobo



There are no burn marks on the back of the motherboard for all I can tell.

Like I said: The motherboard was working fine up until now, and I'm pretty sure everything is connected correctly.

Help is very appreciated, with suggestions on better motherboards even more so (preferably within the $100 range).

Thanks.

Have you correctly plug in the PSU power connector? Try to triple check everything

Sounds like either a Capacitor went, thick smoke and smells very putrid, or a Mosfet melted under the heat sink. Either one will require a major repair. Both help with the voltage to the CPU, so I recommend Testing the CPU on a known good board before replacing the board to ensure a working CPU.

Even though MSI claims that your motherboard supports the FX 8350 CPU on their support page, they have also stated that the FX 8350 exceeds the power delivery circuitry of the motherboard when under full load. You overheated a MOSFET to the point of failure.

The long and the short of it, those two parts do not belong paired together. The result is the power delivery circuitry will very likely fail, as yours has.

There is zero point repairing the motherboard for use with your current processor as it's power delivery circuitry is inadequate.

As has been mentioned, testing the CPU with a known working motherboard is recommended before investing in another motherboard, as you may have more than one dead component now.
